Man squeezed officer's genitals while resisting arrest

A ROMA meth dealer punched a police officer, grabbed him by the head, pushed him to the ground and squeezed his genitals as he violently resisted arrest.

The senior constable was in "immense pain and discomfort" as a result of the attack.

Christopher James Beck, 29, has pleaded guilty in Brisbane Supreme Court to serious assault, assaulting or obstructing an officer, possessing a knife in a public place, possessing a commercial quantity of methylamphetamine and possessing drug utensils.

On the night of December 19 last year, police pulled over Beck south of Roma.

The father of five denied having anything illegal, but an officer spotted him removing a glass pipe from between his legs.

Officers began searching Beck's car and found a knife. He then began the violent assault on the senior constable.

Police also found 14.092g of methylamphetamine, a second glass pipe and notes with names and contact details relating to drug supply.

Some of the drugs were divided into "salable quantities" in clip seal bags.

Defence barrister Timothy Ryan conceded the quantity was commercial, but said Beck was a drug addict who would have used some of it himself.

Crown prosecutor Noel Needham said Beck was on a number of suspended sentences at the time.

His client had drug offences dating back to 2011 and had previously obstructed a police officer.

In that incident, Beck had been in custody when he complained of chest pains and was taken to Roma hospital. When his handcuffs were removed he ran away and was at large for a number of days.

Mr Ryan said Beck had well below average intelligence and had been unable to overcome his drug addiction. He had been attending Narcotics Anonymous in jail.

The addiction had placed strain on his relationship, but the court heard Beck's partner of 12 years still supported him.

Justice Peter Flanagan said Beck's low cognitive ability and tendency to be impressionable meant he had struggled to say no to people wanting to buy drugs from him.

The justice said Beck had been a "model prisoner" and taken steps towards rehabilitation.

Two and a half years of previously suspended sentences were activated. Beck was sentenced to a further 18 months in jail, bringing his total sentence to four years.
